EMERSON GODDARD, OF NEVVYORK, N. Y.

IMPROVED GLUE. y

lowing is a full, clear, and exact description of the same, and of the method of producing it,l referenceV being had to the accompanying drawings, in which- Figure l represents a perspective section of abreaking-mill employed by me in the production of my new manufacture; and Fig. 2 represents a plan of portions ofthe breakingrolls thereof. Fig. 3 represents a perspective section of the finishing-mill employed by me, and Fig. 4 a plan of portions ofthe finishingrolls thereof.

As the glue of commerce is found in the market a considerable time is now consumed by artisans in the preparation of this glue of commerce for use in their various manufactures-first, in water-soakingin cold water, and afterward in heating the glue in a hot-water bath. I havein my invention endeavored to save to the artisan the time heretofore required in such preparation by reducing the time required for the proper dissolving of glue to less than ve minutes, which process has formerly requiredsome hours to do it properly, and also to greatly diminish the chance of bad glueioints from the use of imperfectly-dissolved glue, so likely to occur with hasty and impatient mechanics. Y Moreover, all the various articles of dry glue and gelatine heretofore in use are in a great measure uniitted for domestic use by reason of the long period of time consumed in their proper preparation for adhesive and for dietetic purposes. A great inconvenience has also been heretofore expe rienced by the merchant in the retailing ofthe ordinary glue of commerce from the great difiiculty with which small packages are now made up, (and by hand only,) by reason of the cutting of the wrapping by the sharp angular corners and edges ofthe broken iakes of glue, causing much waste of time and stock.

My invention obviates all of the above objections to common glue; and it consists in an article of glue which does noty require to be prepared for solution by soaking, can be dissolved so as to be ready for use in large quantities for mechanical use in less than five minutes, and in small quantities for domestic use in less than one minute, and can be put up in small packages, by machinery or by hand, of uniform size, and of regular form and weight, similar to those in which ground spices and other like articles are put up (or prepared and boxed) for domestic use and to be sold by retail merchants.

My invention is, moreover, superior to the glue of commerce heretofore in use in that it has an appearance more pleasing to the eye, and by it glues of the s'ame grade have a whiter apparent color, and are therefore more merchantable and bring a higher price.

The best process which I have devised for making such instantaneous glue and the apparatus or machinery I use in the said manufacture, and for which machinery I intend making other and further applications for patents on the novel parts of the same, the said novel parts being applicable to the working of other substances than those used in the manufacture of the aforesaid instantaneous glue, are as follows:

Fig. lis a vertical perspective section showing one-half of what I call a breaking machine.7 It consists of a hopper, a a, into which are mounted two saw-rolls, b b, said rolls running in the direction indicated by the arrows c c, and being mounted in the frame of said hopper a a in suitable bearings, and driven by power pulleys, gears, or other suitable mechanism. Fig. 2 is a plan of a section of these saw-rolls, b b being rings of saw-teeth, d, the axis on which they are mounted; e e, blank rings between the saws, and about twice as thick as the ring of teeth, the saw of one roll ruiming opposite the blank of the other roll alternately through out. f f are rows of pins on either side of the hopper a a, meshing in between the saws, to prevent the contents of the hopper from falling out at the openings that would be otherwise formed by the spaces between the saws, and also to prevent the saws from fouling with any matter that might otherwise be retained between the saws during their revoln` tion.

Into the hopper of this machine I put the ordinary glue of commerce, and by the rotation of the toothed saw-rolls crush the glue into small quite uniform pieces about half the size of barleycorns.

The coarse stock thus prepared I then sub ject to the action of a tine cutting machine. (Shown in vertical perspective section at Fig. 3 l This machine consists of a hopper, g g, in the lower part of which run the two raspingrolls, h h, in the direction indicated by the arrows i i, being impelled by appropriate mechanism. Above these rolls, and a little distance therefrom, is a stationary guide-bar, j, and the previously-ln'oken gluestock,being placed in the hopper, is by rotation of the rasping-rolls brought under the said guide-bar to be acted upon by the teeth of the raspingrolls. rIo retain this glue-stock under the guide-bar until it is fully worked, another bar, lo, which I call a stop-bar," is placed beneath the rolls and between the same. The gluestock is retained between the two bars until it is line cut to the proper degree, when it passes oft' between the stop-bar k and the rolls to a receptacle placed beneath the machine.

Iiig. 4 shows a plan of a section of the rasping rolls h li, with the position and form of the teeth or rasp surfaces by which the fine cutting is done. Each roll is divided into sections of about one inch in length. On the periphery in each section are rows of teeth l l, about six or eight to the inch of length, and the rows about four to the inch of lcircumference. The rows run at an angle of about fortytive degrees with the axis of the rolls, an l the teeth are cut at right angles with their rolls, or forty-tive degrees with the axis of the iolls in the opposite direction to the rows.

Every other section of these rolls has its teeth cut to right or left, contrary to the adjoining sections, so as to give the full row of the teeth a zigzag position on the surface of the complete roll, said zigzag position being shownin Fig. 4.

The object sought to be attained in placing the rows of teeth at opposite angles is to mass the glue-stock in sections or small bodies, so as that it can be wholly cut without long-continued contact with the teeth at anyl given point, and to thereby avoid heating the glue,

and also to keep all parts in a constant equah izing motion, to supply the discharge and to further prevent heating.

The object attained by placing the teeth l l at so great an angle is to cause thel glue as cut to slide oft' the teeth without adhering thereto and consequently gumming up the machine, and also to enable t-he teeth to more thoroughly fracture all the particles of glue while in the act of cutting them off from the mass of gluestock in the hopper, upon the proper fracturing of which particles the readily-solvent properties of the instantaneous glue in a great measure depends. The form of each tooth should be such as to give to each particle of glue cut oi' a curved scale-like form, which renders the rasped glue a loose, light, open, uncompact mass which while in the course of solution will remain thus loose, light, open, and uncompact until quite dissolved.

When it is required to run these machines at a high rate of speed, the stock is intcrmixed with a portion of rye-flour, starch, or any other subst-ance which will in a measure prevent heat and also serve to adulterate and cheapen the product without materially destroying the good qualities of the glue for the purpose of its intended use.

The nature, therefore, of my invention, and what I desire to secure by Letters Patent, is any of the gelatinous or glutinous substances commonly called glue77 so produced as herein described by a process of disintegrational fine cutting, akin to rasping, which shall make the particles thereof thin, scale-like, curling, and thoroughly fractured, so that they form a loose uncompact mass, readily permeable to and solvent in hot water.

This instantaneous glue I intend as a substitute for all kinds ot' liquid and dry glues for family, mechanical, manufacturing, and dietetic uses; and I expressly desire herein to disclaim as any part of my invention each and all of those di'erent preparations of deodorized glue for dietetic purposes made and sold under the names of gelatine,77 `(loopers Gelatine,7 die., which preparations are usually cut from undried or soft stock; hence their particles are unfractured particles, and therefore do not possess the important solvent and packing qualities of my instantaneous glue.

I claim as my invention and desire to secure by Letters Patent- The instantaneous glue herein described as a new article of manufacture.

In testimony whereof I have hereunto subscribed my naine.

EMERSON GODDARD.
